One of my favorites. I review this series over and over. It is such fun!
Both are great, but I mostly listen to books while I am busy with other things.
I have listened to it many times.
Yes. There are so many twists and turns you need to pay attention. I often get distracted while driving and need to rewind.
There are many reasons why a book might be unavailable.
Sometimes a book goes temporarily out of print - and sometimes no audio version has ever been recorded. Audible wants to give you the most complete selection we can and we'll keep adding series and filling in gaps as quickly as possible.
